Major Spoilers For Star Wars Catalyst Follow

Could a reveal in the recently released Star Wars Catalyst: A Rogue One Novel indicate that Coruscant will appear in Rogue One..?

Let me start by pointing out that I haven't yet completed Catalyst, so I'm working from some information that about halfway through the book.

Spoilers follow

We heard in an early excerpt from Catalyst that Orson Krennic would deceive Galen and Lyra Erso into working on the Death Star project, but telling them that their research would be applied to an altruistic cause. This plays out in the first half of the book and results in Galen being placed in a research facility that has been built in an area of Coruscant that is close to the surface. The region (5 kilometres square) was a preserve for an alien race that had lost its home planet. I'm listening to the audio book, so going back and getting details is challenging.

But this is what is said:

There is area in the western hemisphere halfway between the pole and the equator, where one could still stand on the planet’s undisturbed surface.

An area where climate control had yet to over rule nature

Originally a stretch of privately owned grassland left undeveloped because of complicated legalities, the area had ultimately been acquired by the former republic to serve as a sanctuary for a small group of sentients known as the Banquora (sic).

And...

Air control stations and surveillance towers were erected. A landing field was carved into a stand of towering buildings nearby to facilitate the arrival and departure of researchers and material.

Now the only beings allowed access had been throughly vetted by COMPNOR.

The facility itself was like something out of a dream. One of his own [Galen’s] in fact. The main building was a colossal multilevel cube. The roof of the complex was level with the top of the high wall that enclosed the complex.

My feeling is that the research facility is the installation we see Krennic and Galen at in trailer two. See below.

Now if that is the case and this is the Imperial research facility on Coruscant, does that mean that the following images are also based in that location?

Could the third act of the movie could be built around Jyn trying to rescue Galen from this facility on Coruscant, and that is why we see Chirrut Imue and Baze in some of these images, because she has drafted in the Rogue One team to help her. Remember that we heard that Darth Vader would be kicking ass in a rainy setting and that this would make up the lion's share of the Darth Vader footage in this film? Well what if he is on Coruscant to take care of Jyn, Galen and the Rebels?

Whatever happens, I have a solid feeling that we will be seeing Coruscant onscreen again in Rogue One.

I still have 5 hours the audio book to go, so maybe there will be development that make everything one just written moot, but I guess we will see soon enough.
